Gastroenterology Bill Explained

What this document usually means

A gastroenterology bill covers services related to the digestive system. Common charges include office visits, colonoscopies, upper endoscopies, and biopsies taken during procedures. You typically receive separate bills from the gastroenterologist, the facility where the procedure was performed, the anesthesiologist, and the pathology lab if biopsies were taken.

The most important billing distinction in gastroenterology is between screening and diagnostic colonoscopies. A screening colonoscopy for a patient with no symptoms and at recommended age should be covered as a preventive service with no cost-sharing. A diagnostic colonoscopy for symptoms or follow-up of a previous finding has standard cost-sharing.

The first things to check

Check whether your colonoscopy was coded as screening or diagnostic. If it was meant to be a screening but a polyp was found and removed, some plans reclassify it as diagnostic and apply cost-sharing. This is a controversial billing practice that varies by plan and state.

Verify that the facility, gastroenterologist, and anesthesiologist are all in-network. Confirm the pathology charge if biopsies were taken. Count the number of biopsies billed and compare them to the procedure report.

Common reasons this letter feels confusing

The screening-to-diagnostic reclassification is the single most confusing aspect of GI billing. You schedule a routine screening colonoscopy expecting it to be free, and then receive a bill because a polyp was found. Federal guidance and the Affordable Care Act have clarified that polyp removal during a screening colonoscopy should still be covered as preventive, but not all plans comply fully.

Receiving four or five separate bills for one colonoscopy, from the gastroenterologist, facility, anesthesiologist, pathology lab, and sometimes a consulting physician, adds to the confusion.

What to do before you pay or respond

If your screening colonoscopy was reclassified as diagnostic and you were charged cost-sharing, contact your insurance company and cite the ACA preventive services requirement. Ask for the claim to be reprocessed as a screening with polyp removal.

For diagnostic procedures, compare all bills to their corresponding EOBs. If the pathology lab was out-of-network, ask the gastroenterologist's office about having the claim reprocessed through an in-network lab.
